PORTLAND, Ore. -- Guard Bryce Pressley scored 16 points, and four other Portland players finished in double figures as the Pilots upset 22nd-ranked Gonzaga 82-73 Thursday night.
The loss snapped Gonzaga's 22-game winning streak in West Coast Conference games. Portland (10-7, 2-3 WCC) lost its previous 20 games to Gonzaga (14-3, 4-1) since a 2003 victory. The Bulldogs began the night 34-1 against the Pilots since 1997.
The Pilots, who dropped 11 straight games to Top 25 opponents since beating No. 22 Minnesota in 2009, led from the opening basket. The Bulldogs were playing their second true road game of the year.
Gonzaga, the NCAA Division I leader in 3-point shooting percentage coming into Thursday's games at 44.3 percent, sank just four of 15 shots (26.7 percent) from beyond the arc. Portland converted eight of 14 3-point attempts (57.1 percent).
Guards Alex Wintering (14), Kevin Bailey (13 points) and Bobby Sharp (12) joined Pressley and center Thomas van der Mars (11) in double figures for the Pilots.
Center/forward Sam Dower Jr., continuing to rebound from a back injury, came off the bench to lead Gonzaga with 14 points. Guard Kevin Pangos scored 12, and center Przemek Karnowski and guard Gerard Coleman added 11 apiece.
The Pilots were inspired by a near-capacity crowd of 4,714 at the Chiles Center. Portland was averaging 1,376 fans at home games, with a previous high of 2,304.
Bailey put Portland ahead to stay when he opened the scoring with a 3-pointer. His 10 points helped the Pilots build a 39-31 lead at the half.
The 39 points were one short of the first-half season high by a Gonzaga opponent. The Bulldogs led Chaminade 58-40 at halftime in a 113-81 victory on Nov. 26.
Gonzaga made just one of five 3-point tries in the first half. Bailey drained two of Portland's three treys in the first two minutes, and the Pilots finished the half 5-for-9 from beyond the arc.
